Polypropylene is a thermoplastic polymer made from the monomer propylene. A monomer is a small molecule that can be chemically bonded with other monomers to form a polymer. PP is renowned for its toughness and is highly resistant to chemical solvents and acids. It is normally tough and flexible, especially It can be made translucent. It is often opaque and can be colored using pigments. PP also has high fatigue resistance.


 Our company intends to focus on developing PP products because we feel strongly that the environmental advantages of this material, with a far better capacity for re-use and recycling, make it superior to other materials. We are fortunate that it also appeals to clients with its attractive appearance and functional benefits, which offset its higher cost of production. However, we believe these costs will gradually reduce in time, resulting in PP products becoming the preferred material for the food container industry.   


 To meet high customer demand from niche areas of the catering industry, KSIC continues to manufacture good quality of polystyrene products at our Hong Kong factory. This is a highly competitive aspect of our business, with many factories manufacturing PSP products in China.  With our quality manufacturing and professional business practices, we have maintained a solid customer base for PSP products in Hong Kong, China and around the world.


Polystyrene is an aromatic polymer made from the aromatic monomer styrene, which is a liquid hyrdro-carbon commercially manufactured from petroleum. It is one of the most widely used plastics and is a colorless, hard plastic with limited flexibility. It can be cast into molds with fine detail, colored or made transparent. PSP is widely used in food container industry.


While PSP can be recycled, it is often not included in recycling programs because of its light weight, particularly if foamed, and low scrap value. There is also a lack of consumer awareness regarding suitable recycling facilities and collection methods where they do exist.  Expanded polystyrene scrap can be easily added to products such as EPS insulation sheets and other EPS materials for construction applications. When it is not used to make more EPS, foam scrap can be turned into clothes hangers, park benches, flower pots, toys, rulers, stapler bodies, seedling containers, picture frames, and architectural molding from recycled PSP.
